The length of the periodicity, in cm for x and y, in degrees
for phi. Periodicities in phi must divide 360 degrees, they
are rounded if that is not the case.
Periodicities in r are not permitted.
The position of the plane, in cm for x, y and r, in degrees
for phi. The r coordinate of a circular plane must be > 0.
The potential of the wire or the plane in Volt [default 0 V].
A single character which indicates the type of the wire. This
code is used by SELECT to single out wires for special handling.
The code 'S' has a special meaning in that these wires are by
default selected.
The location of the wire, a set of two numbers (x,y) or (r,phi)
depending on whether the cell is entered in polar or Cartesian
coordinates. x, y And r have to be in cm, phi is in degrees.
